Question

0.8z-0.3 (z+10)=0.5 (z+1) ayudemen

Answer 1

 0.8z + -0.3(z + 10) = 0.5(z + 1)
 
 0.8z + -0.3(10 + z) = 0.5(z + 1) 0.8z + (10 * -0.3 + z * -0.3) = 0.5(z + 1) 0.8z + (-3 + -0.3z) = 0.5(z + 1)

  -3 + 0.8z + -0.3z = 0.5(z + 1)

  0.8z + -0.3z = 0.5z -3 + 0.5z = 0.5(z + 1)

  -3 + 0.5z = 0.5(1 + z) -3 + 0.5z = (1 * 0.5 + z * 0.5) -3 + 0.5z = (0.5 + 0.5z) Add '-0.5z'

 -3 + 0.5z + -0.5z = 0.5 + 0.5z + -0.5z

  0.5z + -0.5z = 0.0 -3 + 0.0 = 0.5 + 0.5z + -0.5z -3 = 0.5 + 0.5z + -0.5z

 0.5z + -0.5z = 0.0 -3 = 0.5 + 0.0 -3 = 0.5

 -3 = 0.5
suerte ahora yudame con unos conuntos xD
